Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask film using a heat-melt transfer medium for writing a mask image on color photographic paper.

[0002]

2. Description of the Related Art For example, a mask film may be used for printing characters on a postcard photograph, or may be used for producing a PS plate in the printing field.

The mask film is produced mainly by computer typesetting using a silver salt light-sensitive material, but the silver salt light-sensitive material has processing steps such as exposure, development, etc., which complicates the production process and is expensive.

Therefore, a method of making a mask film using a heat-sensitive transfer medium is proposed in Japanese Utility Model Laid-Open No. 62-162053.

[0005]

When a mask film is formed using such a heat-sensitive transfer medium and a mask image is printed on a color photographic paper using this mask film to create a photograph, the mask image portion of the mask film is formed. Since this is transparent, the mask image of the created photograph has only black color, and it has been desired to color the mask film.

Further, since color photographic paper is not designed for mask image printing, it is difficult to correct the exposure conditions at the time of printing, and especially the exposure conditions for creating an image combined with a photographic negative film. Is difficult to correct.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a mask film using a heat-melt transfer medium that colorizes a mask image and makes correction of exposure conditions for printing easy or unnecessary. Has an aim.
